These are four types of masking tape from mt., Kamoi Kakoshi. Two of them are from the early days, and the rolls are 10m long, not the current 7m. The size is different. I think they are valuable because they are no longer available. The other two are from the 7m roll mt. deko series. They will be shipped in OPP bags to prevent them from getting wet. Anonymous shipping. I also have other masking tapes for sale. From my collection.
